Summary

E.ON

Germany · AI-generated

business energy corporate germany

The AS handle RWE is held by E.ON Verwaltungs GmbH.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames INNOGY_001 and VEW-I-NET associated with the registrant E.ON Verwaltungs GmbH.
  • The AS announces 24,832 IPv4 addresses across 14 prefixes and 2 IPv6 prefixes, while maintaining only 2 observed neighbours, indicating a large internal corporate estate rather than a transit or access network.

Notable

  • All registrants in the RDAP data are listed as E.ON Verwaltungs GmbH, with hostmaster references to innogy SE, aligning with the current corporate structure.
  • E.ON was formed from the 2016 merger of E.ON and RWE, with the RWE brand retained for the energy supply business; the AS handle RWE reflects this historical lineage.
  • The inventory consists of a mix of /19, /20, /21, /22, /23, and /24 blocks, primarily in the 153.100.0.0/16 and 193.25.0.0/16 ranges, showing fine-grained subdivision typical of a large enterprise.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,852 prefixes, as published 2026-11-08. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
